Among the various anions, only cyanide induced the revival of fluoresecence of -Cu(2+) resulting in "Off-On" type sensing of cyanide, which can be monitored at pH 7.4 in 100% aqueous system, and has been applied to a microfluidic platform, in which fluorescent sensor -Cu(2+) displayed green fluorescence upon the addition of cyanide, the in vivo imaging of cyanide using Caenorhabditis elegans.
在各种阴离子中，只有氰化物能使-Cu(2+)的荧光恢复，从而实现对氰化物的“关-开”型传感，这种传感可在pH 7.4的100%水性体系中监测，并且已应用于微流控平台，在该平台中，荧光传感器-Cu(2+)在添加氰化物时显示绿色荧光，还用于秀丽隐杆线虫对氰化物的体内成像。
